Holographic transmitarray antenna with linear polarization in X band [PDF]
AEU - International Journal of Electronics and Communications, 2021 For the first time, we present the design and demonstration of holographic transmitarray antennas (TAs) based on the susceptance (reactance) distribution in this paper. According to the holographic theory, the amplitudes and phases of electromagnetic waves can be recorded on a surface, and then they can be reconstructed independently.
